Regarding participating in larger projects, I would really like recommendations from the PerlMonks on a general purpose, production-ready (or nearly so) web-based CMS written on top of a modern perl framework (Catalyst, Dancer, Mojolicious, or even CGI::Application). Something with good documentation, enough function to be generally useful, and an easy, well documented means to extend functionality with a relatively gentle learning curve.

Perhap a modern perl take on Drupal (Druperl)? Of course not a Drupal clone, but something in that space: useful out-of-the-box, with an entry into extending in a systematic manner. Having a supportive user/developer community is a big plus.

I've looked at miril (CGI-App), ShinyCMS (Catalyst), and the Galileo (Mojolicious) perl CMS's on GitHub, but they are fairly alpha stage right now. I'd really like to see a project like those with wide perl community support. It could be a great learning tool and "gateway app" for aspiring perl programmers.
